CC3235MODSF LaunchPad™ Development Kit (LAUNCHCC3235MOD)
2.2.11 Sense on Power (SOP)
The CC3235MODx device can be set to operate in four different modes based on the state of the sense
on power (SOP) lines. The SOP lines are pins 23, 24, and 34 on the CC3235MODx module. Table 6
shows the state of the device and Figure 14 shows the SOP jumpers.
Table 6. SOP[2:0]
Binary Value Function
100 Flash programming
000 Functional mode + 4-wire JTAG
001 Functional mode + SWD
010 Functional mode + flash
NOTE: SOP[2:0] corresponds to J18 on the LaunchPad design.
Figure 14. SOP Jumpers (Default Setting Shown)
NOTE: Placing no jumpers on the block ensures that the line is pulled low using 100K pull down
resistors. Placing the jumper pulls the pin high using a 10K resistor.
